Which statement is a key principle of motor learning theory?

• A. Practice is optional
• B. Intrinsic feedback is the only form of feedback
• C. Continuous problem solving occurs in learning
• D. Practice is essential, including variability of practice

Answer: (D)

This question centers on how practice structure influences skill acquisition in motor learning. The best principle is that practice is essential, and it should include variability.

Deliberate, repeated practice builds the neural patterns and motor schemas needed to perform skills smoothly. In hippotherapy, variability matters because the horse’s movement, speed, and environment change from session to session. Practicing the same task under different conditions—different horses, different terrains, different tasks—helps the learner generalize the skill and adapt to new, real-world situations, rather than just performing well in a single, familiar context.

Intrinsic feedback is valuable, but learning is often enhanced when learners experience a range of contexts and task demands, not reliance on one narrow scenario. Likewise, insisting that learning is only about ongoing problem solving or that practice is optional does not align with motor learning theory.
